Ahh! This is how I change this!
I always enjoy "can you teerrnnn the air up?"
....*blink* hotter or colder?
We have the option on the Dash to give the FA control of the temp but half the time they go to the extreme and we have to take it back. Nothing like seeing the duct temp at 60*C and rising, then the associated duct overheat annunciators, then curse words, then a click back into cockpit control on the temperature knob .
...
Then five minutes later, they call upfront: "So I have the heat on as hot as it will go and we're still freezing back here". :facepalm:
